JET MT300-4 Electric 2-Speed Trolley – 3 Ton, 3-Phase, 460V
Product Overview
The JET MT300-4 is a heavy-duty electric trolley designed to provide powered horizontal movement for loads up to 3 tons (6,600 lb). Operating on 460V, 3-phase power, it is built for demanding industrial material-handling applications and is designed to pair with compatible JET TS Series electric hoists.
Its two-speed travel system provides a high speed of 79 FPM for moving loads efficiently and a low speed of 20 FPM for more controlled positioning. The trolley also accommodates beam flange widths from approximately 5 to 7 inches, with optional kits available when wider beam compatibility is required.
Key Features
3-ton / 6,600 lb rated capacity for substantial overhead material handling.
460V, 3-phase electrical configuration for industrial power systems.
Two travel speeds of 79 FPM and 20 FPM provide a balance of speed and positioning control.
0.8 HP high-speed motor and 0.2 HP low-speed motor provide powered trolley movement.
5–7 inch standard beam flange range accommodates common I-beam configurations.
Optional flange extension kits can expand beam compatibility for wider flanges.
Minimum curve radius of approximately 78.7 inches (6.56 ft.) helps determine suitable runway layouts.
1-1/2-inch wheel diameter is designed for the trolley's 3-ton capacity.
Approximately 5-inch wheel-to-hook mounting dimension helps maximize available headroom.
IP55 trolley rating and IP65 pendant rating provide protection suitable for specified indoor and outdoor operating environments.
Four-button pendant option can allow control of both the trolley and compatible hoist from one controller.
Direct lug mounting to compatible TS Series hoists helps maximize headroom.

JET's technical documentation lists the MT300-4 as a 3-ton model with 79/20 FPM travel speeds, 0.8/0.2 HP motors, a 5–7 inch flange range, and a 78.7-inch minimum curve radius.
Two-Speed Travel for Better Control
The MT300-4 is designed around the practical need to combine fast load movement with precise positioning. At 79 FPM, the high-speed setting helps move materials efficiently along the runway. Switching to the 20 FPM low-speed setting gives the operator greater control when approaching a workstation, machine, storage position, or loading area.
This two-speed arrangement can help reduce abrupt positioning and makes the trolley more versatile for repetitive material-handling tasks.
3-Ton Load Capacity
With a rated capacity of 3 tons, or 6,600 lb, the MT300-4 is designed for substantial industrial loads. Its two travel motors provide 0.8 HP at high speed and 0.2 HP at low speed, giving the trolley the power required for its two operating modes.
The 6,600 lb rating refers to the trolley's rated load capacity. The complete lifting system—including the hoist, runway beam, connections, and supporting structure—must also be properly rated for the intended load.
Beam Compatibility
The standard MT300-4 accommodates beam flange widths from approximately 5 to 7 inches. JET also offers expansion kits for applications requiring greater flange widths.
Before installation, the beam flange dimensions and structural capacity should be verified against the trolley's requirements. The specified 78.7-inch minimum curve radius should also be considered when designing or selecting a curved runway.
Built for Industrial Environments
The MT300-4 uses a heavy-duty steel construction and is specified with an IP55 rating for the trolley and IP65 rating for the pendant, making the system suitable for the operating environments specified by JET.
The trolley's approximately 5-inch wheel-to-hook mounting dimension also helps keep the hoist and load relatively close to the supporting beam, which can be useful when available headroom is limited.
Hoist Compatibility
The MT300-4 is designed for use with compatible JET TS Series electric hoists. A four-button pendant can provide a convenient control arrangement for operating both the hoist and trolley from a single controller.
It is important to note that the MT300-4 is a trolley rather than a complete lifting system. A compatible hoist, properly rated runway or beam, suitable electrical supply, and correct installation are required for safe operation.
Typical Applications
The JET MT300-4 is suitable for:
Manufacturing facilities
Machine shops
Metal fabrication operations
Industrial maintenance departments
Warehouses with overhead crane systems
Equipment handling
Production material movement
Heavy-load positioning
General industrial material handling
Why Choose the JET MT300-4?
The JET MT300-4 Electric 2-Speed Trolley combines a 6,600 lb capacity, 460V three-phase power, and two-speed travel in a compact overhead material-handling design. Its 79/20 FPM travel speeds allow operators to move loads quickly when needed while retaining a slower setting for more precise placement.
With its 5–7 inch beam flange range, 0.8/0.2 HP motor system, IP55 trolley protection, IP65 pendant protection, and compatibility with JET TS Series hoists, the MT300-4 is a capable choice for demanding industrial lifting and load-positioning systems.
